CVE-2025-27822 Details
Description
An issue was discovered in the Masquerade module before 1.x-1.0.1 for Backdrop CMS. It allows people to temporarily switch to another user account. The module provides a "Masquerade as admin" permission to restrict people (who can masquerade) from switching to an account with administrative privileges. This permission is not always honored and may allow non-administrative users to masquerade as an administrator. This vulnerability is mitigated by the fact that an attacker must have a role with the "Masquerade as user" permission.
A critical access bypass vulnerability has been identified in the Masquerade module for Backdrop CMS, affecting versions prior to 1.x-1.0.1. This vulnerability allows users to temporarily switch to another user account, potentially masquerading as an administrator. The issue arises because the module's permission to restrict non-administrative users from accessing admin accounts is not consistently enforced. To exploit this vulnerability, an attacker must have a role that includes the 'Masquerade as user' permission.
Users are advised to upgrade to the latest version of the Masquerade module. The updated version can be downloaded from the Masquerade releases page.
